“…An aqueous plant extract of E. alata has proved efficient when used as a reducing and capping agent for the synthesis of copper oxide nanoparticles [187]. Similarly, other Ephedra extracts have been used to prepare various types of composite nanoparticles [187][188][189][190]. A bright future may be anticipated in front of Ephedra plant extracts in medicine, green chemistry, and the food industry.…”

Ephedra species are among the most popular herbs used in traditional medicine for a long time. The ancient Chinese medical book “Treatise on Febrile Diseases” refers to the classic traditional Chinese medicine prescription Ge Gen decoction, which consists of seven herbs, including an Ephedra species. Ephedra species are utilized all over the world to treat symptoms of the common cold and coughs, and to combat major human diseases, such as asthma, cancers, diabetes, cardiovascular and digestive disorders, and microbial infections. This study aimed at identifying specific Ephedra species used traditionally in Morocco for therapeutic purposes. The plant parts, their preparation process, and the treated pathologies were identified and analyzed. The results revealed five ethnobotanically important species of Ephedra: Ephedra alata Decne, Ephedra altissima Desf., Ephedra distachya L., Ephedra fragilis Desf., and Ephedra nebrodensis Tineo. These species are used traditionally in Morocco for treating people with diabetes, cancer, rheumatism, cold and asthma, hypertension, influenza virus infection, and respiratory ailments. In addition, they are occasionally used as calefacient agents, to regulate weight, or for capillary care. Few studies have underlined the antibacterial and antioxidant activities of some of these Moroccan Ephedra species, but little information is available regarding the natural products at the origin of the bioactivities. Further phytochemical investigations and clinical data are encouraged to better support the use of these plants.

“…For the synthesis of CuNPs with desired morphologies and properties, a variety of physical and chemical methods have been described, including microwave irradiation, thermal decomposition, sol-gel, colloidal thermal synthesis, sonochemical, hydrothermal, and rapid precipitation. [28][29][30][31] However, these techniques demand a lot of effort, energy, time-consuming approaches, costly, and toxic chemicals.…”

As an additive for diesel engines, copper oxide nanoparticles (CuONPs) are thought to offer a lot of promise. In this work, an experimental investigation was conducted to ascertain the impact on a diesel engine of adding copper oxide (CuO) particles made from a Rubus fruticosus leaf extract product using a novel green synthesis approach. The presence and morphology of the CuO were analyzed by different characterization studies. Subsequently, was investigated the effects of the addition of CuONPs at two concentrations (15 and 20 ppm) on diesel engine performance, brake‐specific fuel consumption (BSFC), carbon monoxide (CO), hydrocarbon (HC), nitrogen oxide (NOX), and smoke emissions. From the experimental outcomes, the D100 + 20 ppm CuO blend shows a significant reduction in CO, HC, and smoke emissions by 58.19%, 25.15%, and 26.67%, respectively, when compared with standard diesel. Also, it was found that the D100 + 20 ppm CuO blend showed better engine performance with enhanced combustion characteristics. The experimental results provided a reduction of around 1.10% in BSFC. This study demonstrates how changes in fuel composition through the addition of nanoparticles to commonly used diesel fuel can provide meaningful improvements in engine performance and emissions.

The present study was performed to synthesize eco‐friendly nickel oxide nanoparticles (NiONPs) from the aqueous extract of Fissidens species (FS) and explore its biological activities. Phytochemicals, namely, alkaloids, flavonoids, sterols, tannins, proteins, carbohydrates and phenols, were present in the aqueous extract of Fissidens sp. The UV–Vis and FT‐IR analyses of FS‐NiONPs revealed a prominent peak at 392 nm, along with functional groups that facilitate the formation of FS‐NiONPs. XRD spectrum confirmed the crystalline nature and SEM with EDX depicted the irregular, aggregated clusters and purity of FS‐NiONPs. The photocatalytic activity against RB94 was achieved within 20 min with maximum decolorization efficiency (93%). The experimental data of adsorption studies fitted well with Langmuir isotherm, showcasing the monolayer adsorption of RB94 through chemisorption process. The thermodynamic study revealed that the dye removal was spontaneous, feasible and endothermic in nature. The results of antimicrobial activity and phytotoxicity study revealed the potentiality of FS‐NiONPs in clinical and agricultural applications. Hence, this study emphasizes the eco‐friendly synthesis of FS‐NiONPs and highlights its decolorization potential, antimicrobial activity and growth promoting properties.
